Abstract

A process for winding a web material such as continuous webs or interleaved web segments into rolls is disclosed. The process disposes a web material on a conveyor belt. At least one winding spindle is disposed proximate the web material disposed upon the conveyor belt. The conveyor belt is adjusted relative to the at least one winding spindle. The web material is then transferred to the at least one winding spindle from the conveyor belt.

Claims (20)

1. A method for rewinding a web material, said method comprising the steps of:

disposing said web material on a conveyor belt;
providing at least one winding spindle proximate said material disposed upon said conveyor belt;
adjusting said conveyor belt relative to said at least one winding spindle;
and, transferring said web material to said at least one winding spindle from said conveyor belt.
2. The method according to claim 1 further comprising the step of operatively associating said winding spindle with a winding turret.
3. The method according to claim 2 further comprising the step of operatively associating a plurality of winding spindles with said winding turret.
4. The method according to claim 3 further comprising the step of sequentially positioning each of said plurality of winding spindles proximate to said web material disposed upon said conveyor belt and transferring said web material to each of said winding spindles.
5. The method according to claim 1 further comprising the step of indexing said winding spindle from a first winding position proximate said conveyor belt to a second winding position proximate said conveyor belt.
6. The method according to claim 1 further comprising the step of disposing a core about said winding spindle and transferring said web material to said core when said winding spindle is proximate said conveyor belt and said web material disposed thereon.
7. The method according to claim 1 further comprising the step of operatively disposing said conveyor belt about a plurality of rollers.
8. The method according to claim 7 wherein said step of adjusting said conveyor belt relative to said at least one winding spindle further comprises the step of moving at least one of said plurality of rollers relative to said winding spindle.
9. The method according to claim 8 wherein said at least one of said plurality of rollers changes a pressure exerted upon said web material by said conveyor belt when said web material is disposed between said conveyor belt and. said winding spindle.
10. The method according to claim 1 further comprising the step of perforating said web material.
11. The method according to claim 1 further comprising the step of providing a web separator, said web separator being adapted to periodically pinch said web material between web separator and said conveyor belt.
12. The method according to claim 11 further comprising the step of providing said conveyor belt with a low coefficient of friction.
13. The method according to claim 11 further comprising the step of providing said web separator with a surface speed that is greater than a surface speed of said conveyor.
14. A method for winding web material, said method comprising the steps of:
providing a conveyor belt, said conveyor belt having a surface;
transferring said web material to said surface of said conveyor belt;
adjusting said conveyor belt relative to a first winding spindle;
subsequently transferring said web material from said surface of said conveyor belt to said first winding spindle; and disposing said web material upon said first winding spindle to produce a finally wound product.
15. A method according to claim 14 further comprising the step of perforating said web material.
16. A method according to claim 15 further comprising the step of separating said web material at a perforation separating adjoining pieces of said web material.
17. A method according to claim 16 wherein said step of separating said web material further comprises the step of providing a separation device for separating said web material, said separation device having a surface speed that is faster than a speed of said web material.
18. A method according to claim 14 further comprising the step of progressing said first winding spindle from a first winding position to a second winding position when said web material is being disposed upon said first winding spindle.
19. A method according to claim 14 further comprising the step of cooperatively associating said first winding spindle with a winding turret.
20. A method for converting a web material into a wound roll, the method comprising the step of:
depositing said web material onto a conveyor belt;
moving said web material deposited upon said conveyor belt proximate to a winding spindle;
adjusting said conveyor belt relative to said winding spindle;
rotating said winding spindle; and, transferring said web material from said conveyor belt to said winding spindle.
